You need to have the vehicle checked for a blocked radiator. This will cause the vehicle to overheat even when there is sufficient coolant in the cooling system. Also if your heater core is blocked (heater not working when there is coolant in the system), this is generally a good indicator the radiator may have a problem with circulating the coolant.

Recently had a rad fluid leak near the rad fluid cap, and added rad stop leak product,and now there is no heat it only blows cold air?

Your stop-leak product may have also "fixed" the heater so no coolant flows there... A not-uncommon side effect of these products.

I have 2003 nissan sentra. poor coolant flow (no heat at idle approx 750rpm). changed t-stat. Comp. chk 1-180, 2-160, 3-160, 4-175 (specs say 198psi). looks like head gasket might be leaking between c

I would agree with your diagnosis if you are loosing coolant into the engine. And the difference between cylinders is more than 25 percent. The standard number of 198 psi is just a reference not a minimum.
Usually if a head gasket is leaking, it leaks compression into the cooling system and makes the engine run hotter than normal along with burning coolant out the exhaust pipe.
Most of the time when you have low heat at idle but normal at road speed, the cooling system is just low on fluid.

2005 Dodge Grand Caravan SE 6 Cyl 3.3L Transmission fluid leaking from cooler lines that is directly in front of the rear right wheel... what is the part these lines go into? I have a big puddle of...

It sounds like you have a couple of issues here, so lets start with the transmission one first. What it sounds like is that you have a busted hose, and the good news is that it is not expensive to repair. You will need to get under the vehicle and find the hose or hoses that are leaking and cut a piece of each hose off so that you can take it to the parts store and get the correct hose to replace it or them. I would recommend getting new hose clamps as well to re-attach the hoses. It also seems that you have some type of radiator leak if your vehicle is running hotter than usual. The leak could be a slow one and that could be the reason that it went un-noticed. The reason that the heater is not working even though the cars engine is hot is that the water that is used to cool the engine is scalding hot and that hot water flows through your heater core and that is how heat can be selected and blow hot air out of the vents. If there is not enough water, then there will not be any heat. This is some thing that you will also want to address immediately as if the engine runs hot due to a lack of water/antifreeze then you will run a high risk of damaging or blowing the motor and that would not be good. My advice is that you locate the cooling system leak and fix it ASAP to avoid some costly damage. A lot of cooling system leaks are, the water pump, radiator cap or bad hoses, so make sure that you check them thoroughly. I hope that you have found this information helpful as that is my goal.

90 legacy, started overheating but was blowing cool air out of the heater even as the needle was pegged. Some fluid in reservoir, top radiator hose felt like it was under a lot of pressure.

Two things would cause this

There is a slow leak and the radiator is low on fluid

Let the vehicle cool down completely and then check the level in the radiator. I bet its pretty low. Top off the radiator with a 50/50 mix of coolant and water. start the vehicle and let it warm up with out the radiator cap on. Keep adding fluid as necessary. While waiting for it to warm up check around for any abvious coolant leaks. Things like hoses, radiator seams, water pump, water inlet/outlet gaskets. If no leaks are found it may be necessary to pressure test the cooling system and even then it might be a slow leak that only occurs when the vehicle is cold.

If the radiator is full than I would suspect that water pump is no longer working or creating enough flow. If the thermostat where stuck you would still get heat. If the water pump is not circulating coolant than you would get no heat and the car would overheat.

My coolant is filling up with transmition fluid why?

Transmission fluid is sometimes cooled by way of a seperate internal tank within your radiator, the fluid is passed through hoses and steel or aluminum tubes from the transmission to the radiator, as the fluid flows thru the internal tank within the radiator it transfers heat from the fluid into the coolant within the radiator which then exchanges the heat from the coolant thru the radiator fins and into the ambiant air around the radiator.
That being said, if the internal transmission fluid tank or the connections at or within the radiator develop some sort of leak, the two fluids(coolant and transmission fluid) will mix and will show up where it shouldn't be! You may have an internal leak within the radiator, which means the radiator needs to be replaced.
Good Luck!

When you bypass the heater core the path for the water to go through the core is gone. Correct?, you have connected to engine water line out to the engine water input? thus bypassing the heater core........

No, you just won't have water flow through the heater core, Coolant flows through the engine through the lower radiator hose as the water pump sucks it out of the radiator and pushes it through the engine. It then flows out the top radiator hose when the thermostat opens. It then flows into the radiator to cool off.

Is your heater core leaking?

Transmision fluid in radiator fluid

Flush cooling system , and get transmission flushed & fluid and filter changed as well. Then install new radiator. Hopefully you caught it before damage to transmission.

My 2004 Mitsubishi Endeavor is overheating, I noticed it last night when I turn the fan on to high heat the gauge will drop to a normal temperature. I checked the fluid level that?s ok, and opened the...


Lot of possible reasons. Some of them very stupid, even though I mention it here, sorry:

1. Thermostat regulating the cooling fluid flow - works correct?
2. Enough cooling fluid? Not leaking from somewhere?
3. Level of engine oil? Its quality? (If dirty or low oil, heat can not spreed into oil - oil is cooling subsatnce as well. If low oil level - you know what, engine is not lubricated etc.)
4. Water pump works correct? No pump, no water circulation.
5. Any dirt in the water circulation system? Piece of rock, shred of rag, maybe some sediments (can figure out only after disassembling the system = lot of garage work).

I had one friend who complained about his mazda MX3 quick overheating. My first question was, if there is cooling fluid and he told me "Of course!!! - I was in the garage yeasterday evening and fluid was refilled." The engine was hot and smoking badly after 3 mins of calm slow ride. Next day he called me with curious finding - there was no cooling fluid at all, was leaking out from the radiator. Thanks for contacting Fixya.
